Table 3a. GMT phases of the major tidal constituents at the St. Petersburg tide gauge and the 12 ADCP stations and the associated time differences between high tide and maximum (shoreward directed) tidal currents for 12 ADCP stations (using speeds of M2, S2, O1 and K1 of 29.98 deg/hr, 30.00 deg/hr, 13.94 deg/hr and 15.04 deg/hr, respectively). "+" and "-" indicate time lags and leads, respectively.
